Global `beforeEach` in jasmine?

问题

I'm using Jasmine to write tests.

I have several test files, each file has a beforeEach, but they are exactly the same.

How do I provide a global beforeEach for them?

回答1:

You can put it in your spec_helper.js file and it should work fine.

回答2:

x1a4's answer confused me. This may be more clear:

When you declare a beforeEach function outside all describe blocks, it will trigger before each test (so before each it). It does not matter if you declare the beforeEach before or after your describe blocks.

It's not mentioned in the documentation.

// Example: 

beforeEach(function() {
    localStorage.clear();
});

describe('My tests', function() {
    describe('Test localstorage', function() {

        it('Adds an item to localStorage', function() {
            localStorage.setItem('foo', 'bar');
            expect(localStorage.getItem('foo')).toBe('bar');
        });

        it('Is now empty because our beforeEach cleared localStorage', function() {
            expect(localStorage.getItem('foo')).toBe(null);
        });

    });
});
